Major Scheme

Part of our programme of improvements (value >10m)

Cost:  £1.5 billion


Scheme update

The government has committed up to £1.5 billion investment to improve the A14 between Cambridge and Huntingdon. This vital upgrade will relieve congestion, unlock growth and help to connect communities.

Proposals include a major new bypass to the south of Huntingdon, widening part of the existing A14 between Swavesey and Girton, widening part of the A14 Cambridge Northern Bypass, widening a section of the A1 between Brampton and Alconbury and demolition of the A14 viaduct at Huntingdon.

A high level map of the route can be found here and a more detailed map can be found here.

Stay up to date with the DCO process

On 27 January 2015 the Development Consent Order (DCO) for the A14 Cambridge to Huntingdon improvement scheme was accepted for examination by the Planning Inspectorate (PINS). The application can be viewed on the National Infrastructure Planning website.

The application is now in the ‘pre-examination’ stage, the period before which Planning Inspectorate starts officially examining the application. The examination will start after the Preliminary Meeting is held, the date of which is yet to be confirmed by the Planning Inspectorate.

The deadline to register your interest in the application has now passed. If you have registered your interest the Planning Inspectorate will keep you updated on the progress of the application.

Otherwise, you can stay up to date with the process by visiting the Planning Inspectorate website and sign up to receive their email updates.

If you wish to make comments on the application but have not yet registered your interest, please contact the Planning Inspectorate via their website.

The approximate timings of the DCO process can be viewed here.

What is happening?

We plan to improve the A14 trunk road between Cambridge and Huntingdon. Our proposals include:

  • widening a section of the A1 trunk road between Brampton and Alconbury
  • removing the road viaduct over the railway at Huntingdon
  • a new bypass to the south of Huntingdon
  • detrunking the A14 between Ellington and Swavesey
  • widening the carriageway on the A14 between Swavesey and Girton
  • a new local access road
  • improvements to the Cambridge Northern Bypass
  • junction improvements

We held a public consultation on route options in September and October 2013 to see what people thought of our proposals for what was at the time a tolled scheme. In December 2013, following the feedback received from the public consultation, government decided that the scheme would not be tolled. Since then, we have been reviewing assumptions and developing more detailed proposals.

In order to seek feedback on our revised proposals, we held a formal pre-application consultation, between 7 April and 15 June 2014, and your further views and comments were sought.

When and where is this happening?

If the development consent for the proposed scheme is granted, construction of the main works would be expected to commence in 2016 and continue for a period of approximately 3.5 years to 2020. Additional works would be carried out to downgrade the existing A14 trunk road to the south west of Huntingdon once the main construction was complete and these would be expected to take a further 12 to 18 months.

The proposed scheme starts at Ellington, on the existing A14 to the west of Huntingdon, and extends to the Milton junction on the Cambridge Northern Bypass. It also includes widening of the A1 between Brampton and Alconbury.

Why is this happening and what will it cost?

The existing A14 trunk road between Cambridge and Huntingdon is well known for congestion and delays

  • Almost 85,000 vehicles use this stretch of the A14 every day; significantly more than the level originally designed for
  • Around quarter of this is heavy goods vehicles - well above the national average for this type of road

The government has made a provision for £1.5 billion of capital investment for this scheme. The proposals will be funded through a combination of contributions from Central Government, local authority and Local Enterprise Partnership.

How will the scheme be carried out?

We are experienced in the delivery of major construction projects and will develop a delivery strategy for the proposed scheme that minimises unnecessary disruption, inconvenience and adverse impacts. We will work closely with our stakeholders, including local authorities and others, to produce a Code of Construction Practice which will identify the specific issues that are likely to occur and the measures that will be used to address them.

What are the benefits?

The proposals for the A14 will:

  • relieve traffic congestion
  • unlock local economic growth
  • enhance national economic growth
  • connect communities
  • improve the environment
  • improve safety and reduce driver stress
  • improve the environment in Huntingdon
  • create a positive legacy for the region

The Proposed Scheme

The proposed scheme consists of:

A1 widening between Brampton and Alconbury

Widening the A1 between Brampton and Alconbury over a length of approximately 3½ miles, from the existing two lane dual carriageway to a three lane dual carriageway. This would be achieved between Brampton and Brampton Hut by constructing a new road to the west of the existing A1, with the existing A1 road becoming part of the new A14 Huntingdon Southern Bypass

A New Huntingdon Southern Bypass

A new Huntingdon Southern Bypass of approximately 12½ miles in length, which would provide a two lane dual carriageway between Ellington and the A1 at Brampton and a three lane dual carriageway between Brampton and Swavesey.

This would remove a large proportion of traffic from the section of the existing A14 between Huntingdon and Swavesey as well as Brampton Hut and Spittals interchange. The new bypass would include a raised viaduct section of road running across the river Great Ouse and a bridge over the East Coast Mainline railway.

It would include junctions with the A1 at Brampton and with the A1198 at Godmanchester

Handing the existing A14 trunk road to the local authority

The Highways Agency currently manage the existing A14. In our proposals, the section between Ellington and Swavesey, as well as between Alconbury and Spittals interchange, will be ‘de-trunked’. This means the road will be given county road status and run by the local authority.

Huntingdon Town Centre improvements

We propose the demolition of the A14 rail viaduct over the East Coast Mainline railway and Brampton Road in Huntingdon. A through route would be maintained broadly along the line of the existing A14 through Huntingdon, making use of the Brampton Road bridge to cross the railway line and by constructing a new link road from Brampton Road to connect with the A14 to the west.

A14 widening

  • Widening of the existing A14 over approximately 5½ miles to provide three lanes in each direction between Swavesey and Bar Hill and to four lanes in each direction between Bar Hill and Girton
  • Widening of a 1½ mile section of the Cambridge Northern Bypass between Histon and Milton

A14 junction improvements

  • Improvement of existing A14 junctions at Swavesey, Bar Hill and Girton to improve the capacity of the road, ensure compatibility with adjacent proposed developments such as Northstowe, and connections for non-motorised users
  • A new local access road, approximately five miles in length, to be constructed as a dual carriageway between Fen Drayton and Swavesey and as a single carriageway between Swavesey and Girton. The road would provide a route for local traffic between Cambridge and Huntingdon as well as providing access to properties and businesses along the corridor

Safeguarding directions have been issued to the relevant local planning authorities; this protects the land required for the proposed scheme from potentially conflicting development. The safeguarding directions can be viewed on the 'Safeguarding Directions' tab above.

If you think your property is subject to compulsory purchase or may be affected by blight, the following documentation will be of help:

Our road proposals and your property - This booklet explains the procedures the Highways Agency follows to deliver major new road schemes. It outlines how you can make representations about the road proposals if they affect your property.

Blight and your property - This booklet provides information about blight caused by major new road schemes and what you can do if your property is blighted.

Compulsory purchase and your property - This booklet explains the different types of compensation available when your property is compulsory purchased as the result of a new road. It also provides information about how the Highways Agency will deal with your claim for compensation.
